This is gourmet action food. If you think Marvel heroes are great, they pale compared to this guy. Or, if you just like watching Nazis get the living shit beat out of them, (I know I do) this is the film to watch. Or maybe you just want to see raped women get empowered for revenge. Sisu has all that. And it's bloody.
I also love words that have no direct translation to English, like the Portuguese word soldade, or the German Schadenfreude. Now I've learned another, the Finnish word Sisu: A white-knuckled courage and unimaginable determination.
